How Can You See an Atom?

Season 2 Episode 18 | 5m 35s

Reactions takes a close up look at the science of how we can see an atom. Since ancient Greek times, philosophers and scientists have tried to figure out what an atom looks like. For a couple thousand years, humans could only speculate on the structure and other properties of the smallest unit of matter. It wasn't until the 1980s that chemists could see individual atoms.
